bookmarks: prevent divergent bookmark from being updated unexpectedly

Before this patch, "@99" suffixed bookmark may be updated unexpectedly
by the bookmark value on the remote side at "hg pull", if all of "@1"
to "@99" suffixed bookmarks exist in the local repository, because
variable "n" still refers "@99" suffixed bookmark after the loop to
examine "@num" suffixes, even though it already exists in the local
repository.

This patch prevents divergent bookmark from being updated
unexpectedly, and shows warning message in such situation.

This patch uses original python script "seq.py" instead of "seq"
command to create sequence numbers in the test, because "seq" command
may not be available: it isn't defined in recent POSIX specification
(POSIX.1-2001 2013 Edition or XPG7)

test that a commit clears the merge state.

  $ hg init repo
  $ cd repo

  $ echo foo > file1
  $ echo foo > file2
  $ hg commit -Am 'add files'
  adding file1
  adding file2

  $ echo bar >> file1
  $ echo bar >> file2
  $ hg commit -Am 'append bar to files'

create a second head with conflicting edits

  $ hg up -C 0
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo baz >> file1
  $ echo baz >> file2
  $ hg commit -Am 'append baz to files'
  created new head

create a third head with no conflicting edits
  $ hg up -qC 0
  $ echo foo > file3
  $ hg commit -Am 'add non-conflicting file'
  adding file3
  created new head

failing merge

  $ hg up -qC 2
  $ hg merge --tool=internal:fail 1
  0 files updated, 0 files merged, 0 files removed, 2 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon
  [1]

resolve -l should contain unresolved entries

  $ hg resolve -l
  U file1
  U file2

  $ hg resolve -l --no-status
  file1
  file2

resolving an unknown path should emit a warning, but not for -l

  $ hg resolve -m does-not-exist
  arguments do not match paths that need resolving
  $ hg resolve -l does-not-exist

resolve the failure

  $ echo resolved > file1
  $ hg resolve -m file1

resolve -l should show resolved file as resolved

  $ hg resolve -l
  R file1
  U file2

  $ hg resolve -l -Tjson
  [
   {
    "path": "file1",
    "status": "R"
   },
   {
    "path": "file2",
    "status": "U"
   }
  ]

resolve -m without paths should mark all resolved

  $ hg resolve -m
  (no more unresolved files)
  $ hg commit -m 'resolved'

resolve -l should be empty after commit

  $ hg resolve -l

  $ hg resolve -l -Tjson
  [
  ]

resolve --all should abort when no merge in progress

  $ hg resolve --all
  abort: resolve command not applicable when not merging
  [255]

resolve -m should abort when no merge in progress

  $ hg resolve -m
  abort: resolve command not applicable when not merging
  [255]

set up conflict-free merge

  $ hg up -qC 3
  $ hg merge 1
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

resolve --all should do nothing in merge without conflicts
  $ hg resolve --all
  (no more unresolved files)

resolve -m should do nothing in merge without conflicts

  $ hg resolve -m
  (no more unresolved files)

get back to conflicting state

  $ hg up -qC 2
  $ hg merge --tool=internal:fail 1
  0 files updated, 0 files merged, 0 files removed, 2 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon
  [1]

resolve without arguments should suggest --all
  $ hg resolve
  abort: no files or directories specified
  (use --all to remerge all files)
  [255]

resolve --all should re-merge all unresolved files
  $ hg resolve -q --all
  warning: conflicts during merge.
  merging file1 incomplete! (edit conflicts, then use 'hg resolve --mark')
  warning: conflicts during merge.
  merging file2 incomplete! (edit conflicts, then use 'hg resolve --mark')
  [1]
  $ grep '<<<' file1 > /dev/null
  $ grep '<<<' file2 > /dev/null

resolve <file> should re-merge file
  $ echo resolved > file1
  $ hg resolve -q file1
  warning: conflicts during merge.
  merging file1 incomplete! (edit conflicts, then use 'hg resolve --mark')
  [1]
  $ grep '<<<' file1 > /dev/null

resolve <file> should do nothing if 'file' was marked resolved
  $ echo resolved > file1
  $ hg resolve -m file1
  $ hg resolve -q file1
  $ cat file1
  resolved

test crashed merge with empty mergestate

  $ hg up -qC 1
  $ mkdir .hg/merge
  $ touch .hg/merge/state

resolve -l should be empty

  $ hg resolve -l

  $ cd ..
